To all whom it may concern:

Be it'known that I, CHARLES FRANCIS JENKINS, a citizen of the United States, residing at Washington, in the District of Columbia,- have invented .certain new and useful Improvements in Paper Receptacles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenableothers skilledin the art to which it appertains to make and use the same.

This invention relates to spirally wound receptacles and has for its object to. produce a cheap and practical liquid proof receptacle which may be opened without cutting the top, and when once opened cannot without great difiiculty be closed again, with the same closure.

k 7 With these and-other objects in view, the

invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals refer to like parts in all the views :'F igure 1 represents a longitudinal sectional view of the completed receptacle.

Fig. 2, a top plan view thereof. Fig. 3, a top plan view of a slightly modified form of closure holding means, .and Fi L 4:, an elevational view illustrating the difliculty that will be experienced in attempting to close the receptacle after it has once been opened.

1 represents a suitable spirally wound body portion preferably conslstingof three layers of material as shown. I

2 represents the disk of an inverted flanged cup closing the lower end of the body portion and having its flanges 3 flush with the lower end of said body portion, thereb providing a space above the lower end 0 the body portion under the disk 2 as shown. 4 represents the disk of a similar flanged cup which is flushwith and closesthe upper end of said bodyportion' while its flanges 5 are inserted inside the receptacle as illustrated. Since the flanged cups closing the ends of the body portion 1 are stamped from paper sheet material the flanges 3 and 5 are-necessarily more or less resilient, and are therefore liable to expand or flatten out if left unconfined. Therefore, in order to get the top disk 4 in place, it is in practice essential that the same be insertecl by means of suitable dies through the opposite end of the tube or body portion 1 and forced along the length of said tube until the said disk 4 and the flanges 5 occupythe positions shownin Fig. 1. After these parts have been so located, then the bottom disk, 2 and flanges 3 are brought into place, 4

and the end of the body' portion closed by these parts is then preferably dipped in paraffin, so as to impart to this end of the body portion 1, the inner strip of parafiin 6 and the outer strip 7 as illustrated in Fig. 1, and at the same time permit the paraffin to extend up between the flange 3 of the closure and the wall of the body portion 1 and thereby seal the said flange 3 securely in lace.

f course, in the above operations after the disk 4 has been placed and before the disk 2 is inserted, the contents of the package must be filled into the body 1. This is accomplished preferably by the same machinery that inserts the disk 2. The flange 5 being unattached to the inside of the body 1, it is held in place by friction, and I have found in practice that with these machine.

made closures, the joint is sufficiently tight to hold milk and other liquids. It is particularly desirable in a milk bottle to be able to separate the cream from the milk, and the closure such as the disk. 4 which may be easily slipped out, fulfils this requirement. But in handling these bottles, it is found the friction between the flange 5 and the inner walls of the body is not as great as may be desired, and therefore there is pro- -vided the strip 8 which passes over the said disk 4, and has its ends held against the body 1 by the band 7 as illustrated. This band is preferably of paper like the body 1, and may be cut by machinery from suitable lengths of tubing. This bottle being filled with milk for example, the housewife may with a fork or other sharp instrument break the band 8, pry open the closure and expose the cream. As soon as she does this support of the tinuous disk 10 is placed over the top closure and crimped' down around the bottle month by means of the ring 9. The parafiin strips 6 and 7 serve to protect the bottom of thebody 1, and the disk 2 from any moisture or water that mi ht be on the shelf or other ottle, and therefore prevents them from collapsing by being wet, while'at the same time saving the paraflin that wouldbe necessary to coat the entire outside. The interior of the bottle however, is provided with the paraflin layer 11 which protects the walls from the contents.

What I claim is:- 1. A paper vessel provided with an inverted cup sha ed flanged closure flush with the top of, an the flange of which is frictionally held under compression inside of said vessel; and-meansindependent of andexterior tosa'id closure for securing the same in place, substantially'as described.

2. A paper vessel provided with an inverted cu shaped flanged closure flush with the top 0 said vessel and having its flange frictionally held under compression inside the same; and an independent fastening means comprising a ring and material passing over said closure or holding the latter in place, substantiall as described.

In testimony'whereof I aflix my signature, in presence of two witnesses.
